My dad just purchased a 1966 Galaxie 500 4dr hard top. Im not really a Ford guy but if its a classic I like it. We are not for sure of engine size nore do I know where to look on the block. Does anyone have any info on this or where can I locate a casting number for the engine. Not for sure 390 or 352.

The ID should be located on the passenger side (right side) and is just above the heater box, where the heater hoses enter and exit. Look for a protrusion along the seam above the fire wall. Its about 8" from the passenger side fender. If it is not there, then it could have been ground off but that is highly unlikely and would be a problem. The ID tag was formed with the firewall stamping and not welded nor bolted or riveted. Look closely.

Don't trust the door ID, the door could have been changed in the past. Of course, even if it VIN's for a 390, that doesn't mean that some meathook hasn't changed it for a 332 or 352 or 360 or 406 or 410 or 427 or 428 or some other hermorphroditic combination of block and crank. Because there were so many different FE motors and because there is good interchangeability between motors, these are among the most difficult to identify without pulling a head to measure the bore and stroke.

It's also possible that the title reflects the VIN on the door, but the body VIN is different, in which case you could be in possession of a previously stolen or salvage title car. Naaah, that could never happen.

The blocks casting number is located on the passenger side of the block slightly above the starter,there will be 3 letters followed by 6015 and another letter(example EDZ-6015-A) for more information and a guide what they mean go to: www.aacncclub.com ,some Fords shared the same block numbers even though they were different cubic inch engines,also look for the code number on the intake and put in Google search.

If you believe the engine to be original, the best thing is to look at the 4th character of the serial number... it should be a letter that is the engine code.
Also if it is a 4 bbl carb is is NOT a 352.
1966 cars also had the engine size on the fender emblem.
